Eternal bachelor George Clooney could finally be settling down — the actor is engaged to beautiful lawyer Amal Alamuddin, sources tell Page Six.

Clooney has proposed to humanitarian lawyer Alamuddin after dating the British beauty for less than a year, we are told.

Alamuddin, 36, was spotted showing off an engagement ring as she and Clooney, 52, dined at Nobu in Malibu on Thursday night with Cindy Crawford and husband Rande Gerber.

A source told Page Six, “George and Amal hoped keep the engagement quiet, but they can’t hide the fact that they are very happy.”

When contacted on Friday night by Page Six, Clooney’s rep Stan Rosenfield didn’t confirm or deny the engagement, simply telling us, “I do not comment on his personal life.”

While actor and Syria activist Clooney has in the past dated models, waitresses and most recently wrestler Stacy Keibler, he appears to have met his match in accomplished Alamuddin.

She studied at Oxford and the New York University School of Law, speaks three languages — French, Arabic and English — and has represented Wikileaks founder Julian Assange in his extradition proceedings with Sweden and is now an adviser to former UN Secretary General Kofi Annan, the special envoy to Syria.

After they were spotted leaving a dinner together in London in November 2013, Clooney initially denied he was dating Alamuddin, saying they were working together on a satellite program for Syria. But in February he took her to a screening of his movie “Monuments Men” at the White House, along with his parents, Nick and Nina Clooney.

Then in March, Clooney and Alamuddin were pictured looking romantic together on a luxury safari vacation watching wildlife in Tanzania, before heading to the Seychelles.

Clooney, who was married to actress Talia Balsam from 1989 to 1993, told Esquire in December that he wasn’t suited to marriage. He said, “I haven’t had aspirations in that way, ever. I was married in 1989. I wasn’t very good at it. . . . I was quoted as saying I’ll never get married again pretty much right after I got divorced and then I’ve never talked about it since.”

He added that while some people think it is strange he does not have children, but he is not in a rush to start a family. He said: “Should I go, ‘I got to get me some kids right now!’ and rush out and impregnate someone? Look, what I do know is that I was raised in a loving, happy family. I don’t have any dislike or distrust of that.”
